"Steve Stephens was spotted this morning by [Pennsylvania State Police] members in Erie County," an official wrote on Twitter, posted at 11:46 a.m. ET. "After a brief pursuit, Stephens shot and killed himself."

Cleveland Police Chief Calvin Williams confirmed Stephens shot himself after Pennsylvania State Police followed a tip leading to Stephens' car that was parked in a McDonald's parking lot. A little after 11 a.m. local time, troopers found Stephens sitting in his white Ford Fusion. Police pulled Stephens over to the side of the road and as troopers approached his car, he shot himself.

“We are grateful to the people that gave this tip to Pennsylvania State Police. ... we are grateful that this has ended," Williams said.

On Monday, several Pennsylvania schools were placed on lockdown following reports of a sighting.

Investigators believe Stephens shot and killed 74-year-old Robert Godwin Sr. on Easter. The killing appeared to be random.

In the video, which appears shaky, Stephens gets out of his car and appears to randomly target Godwin, who was holding a shopping bag. Stephens says the name of a woman, whom Godwin does not seem to recognize.

"She's the reason that this is about to happen to you," Stephens told Godwin before pointing a gun at him. Godwin can be seen shielding his face with the shopping bag.

Godwin's family described him as a good man, while also forgiving Stephens for the shooting.
